Yes. Do this.

I think, especially now as this dep tuning is going on, that the first
step should be to bring out these "big gun" dependencies like: 

BuildRequires; texlive-collection-latexextra

And get stuff working quickly.

After the dust has settled with the transition and deps are even
slightly modularized (from the old "latex"), then maybe at a future
date the Deps can be investigated with more granularity, and
the texlive-collections can be optimized.
